I just watched a special on either National Geographic or Discovery Channel talking about sharks in that position are virtually out of it, literally. They performed a small surgery to implant a sort of GPS device on a small lemon shark and the thing never moved when they made the opening to implant it or stictch it up. Amazing.

I was avoiding saying to much because I do on occasion flip sharks to make them docile this I'm sure is not a politically correct thing. It shuts them down they don't wiggle or squirm, it allows us to examine them more closely.I don't know exactly what this shark had in her mind but often notice them sleeping with their head under a rock in the daytime but never belly up. I joke with other divers asking them if they know how to tell a male shark from a female and tell them to grab the tale ,flip them over and look at the bottom. But seriously this is a female she has a special set of fins around her vagina called claspers that are for the purpose of holding on to the male during intercourse....oops did i really say that?
